to thespring that maybe convenient; and m thereupon. the handle bars will be closed toward each other and effect acorrespo'nd ing movement in the forward ends of :the

.jaws :10, 11 causing said jawsto compress thespring between them. When the spring 20 is in a state of compression itsstrain isv relieved from I the cotter pin 32 and the latter may be removed," and thereupon thetool.

may-be utilized'to lowe'r the spring from while held by the tool-may be reapplied,

be restored to position, whereuponl'the operator will press against the thumbpiece 39 tofree the rack-37 from the loop 38 and,

permit the expansive force of the spring 20 to move the forward portlons of the aw members 10, 11' andthe rear port ons of the handlebars 12, 13 ina direct-ion from each other, the hands of the operator pref 'erably remaining onthe handlebars so; as" to prevent a toosudden action of the spring in regaining-its former COIICllt-IOIL --After. the spring 20 has become expanded, the

tool may be removed therefrom. g j

The tool is composed of few parts and these partsare very durable, being in the.

form, mainly, of'flat bars arranged on edge. The manner of arranging and pivoting the jaw members to the handle bars is alsolmportant, since thereby the forward ends of the jaws may. have a considerable range of movement. The tool is also one of great compactness in that when the handle bars are closed together as nearly as they may be, said bars and the jaws 10,.11-aresubstantially paralleland as close together as the curved innerends of the handle bars and jaws permit, and at this time also the rack 37 folds down close to the upper aw 10 and at its forward'end enters in between the bars l4, 15 of said jaw 10.

I do not limit my invention to all of the details of form and construction shown and described, since I am aware that some of these details may be modified within the scope of the appendedvclaims. I may add also that for some makes of engine the forward portions of'the jaws 10, 11 may be modified in shape, and in Fig. 7.I 11lustrate a modified form of bar for the upper jaw 10. When the bar shown in Flg', 7 is made use of, the other bar for the same jaw will harmonize with the one shown in Fig. 7. The modification consists in extending the forward end ofthe jaw upwardly,.

corresponding with that: shown in Fig. '7'

for one of the jaws 10,- li -the other jaw may retain the shape in which. it is shown in Fig.1; Theforwa'r'd ends ofi the jawmembers 10,- 11 will therefore vary with. re-; quirementsr The jaws' 10, '11, as 'showng2.
